Wolong High-Voltage Variable Frequency Drive Case: GGL-II Project in Karachi, Pakistan | 2240kW Compressor VFD Speed Control

Performance List: Project 009 Project Name: GGL-II Karachi Pakistan MVC Location: Karachi, Pakistan Commissioning Date: 2015, Month 5 Equipment Configuration: 2240 kW, 1 units Load Type: Compressor Process compressors require high torque and stringent starting conditions. High-voltage variable frequency drives (VFDs) enable soft starting and speed control based on process load, eliminating the shock to the power grid and mechanical transmission chain caused by direct-on-line starting. The same platform offers torque limiting, runaway startup capability, and multi-unit redundant bypass functionality, making it suitable for harsh environments such as high temperature and heavy dust. Wolong Electric (Zhejiang) Power Electronics continues to serve the Pakistan market through an authorized distributor network (including K Electric VFD project bidding authorization NO.WLPEFX20260019). Project Value: Representative achievement in the South Asian market, reduced compressor starting impact, smooth process regulation, and supported by a local agency service system.
